Several areas across the West Country, including Bristol, Somerset, Dorset, and Wiltshire, have officially entered a period of prolonged dry weather. Neighbouring regions in Gloucestershire and Hampshire, falling within the Environment Agency’s Wessex operational area, are also affected by this change in status. The declaration comes as environmental impacts from insufficient rainfall and persistently high temperatures become increasingly evident.
Environment Agency officers are anticipating a rise in environmental incidents throughout the summer. These are expected to be driven by critically low river flows, elevated water temperatures, and fish struggling for oxygen as aquatic weeds and algal blooms flourish in the warmer, slower-moving water. Groundwater levels are now reported to be below normal or notably low, with forecasts indicating largely dry conditions for the remainder of July, despite a slight chance of showers later in the month.
Matt Akers, Environment Planning & Engagement Manager at the Environment Agency, highlighted the stark contrast in recent weather patterns. "There’s been a big difference in the environment in the past month," Akers stated. "June had 132% of its typical rainfall. This month we’ve had less than 1% so far." He cited examples such as low river flows in the Hampshire Avon and water temperatures reaching 24C, which he described as "almost tropical." The Environment Agency is actively monitoring the situation and remains prepared to respond to incidents arising from these conditions.
The agency has already been active in mitigating the impact on wildlife, recently assisting in moving hundreds of fish in the River Tarrant in Dorset to safer locations. Plans for weed cutting and vegetation removal are also underway to help alleviate stress on aquatic ecosystems. While the beginning of 2026 saw a wet period, the crucial March to May period delivered below-average rainfall to the West Country. Even June's above-average rainfall did not fully compensate for this deficit, as 82% of it occurred within the first ten days and was not evenly distributed across the region.
The National Drought Group, comprising representatives from the Met Office, government bodies, regulators, water companies, the National Farmers’ Union, and conservation experts, is closely observing the evolving situation. The public is being encouraged to play their part in water conservation. A new campaign, 'Let’s Save Water,' promotes simple methods for reducing water usage at home, such as taking shorter showers, promptly fixing leaks, opting for a bucket or watering can instead of a hosepipe, using a washing-up bowl, and utilising the eco mode on household appliances.
